Monitoring Linux Host Metrics with Prometheus | Node Exporter (Setup, Scrape, Query, Grafana)

In this video, I show you how you can use the Prometheus Node Exporter to monitor Linux (or Unix) host metrics. We first download and run the Node Exporter and then we monitor it with Prometheus. Then, we explore some of the available metrics in Prometheus and show how to import an exhaustive Node Exporter dashboard into Grafana.

I’d love to see how Grafana Alloy fits in to the equation, with examples on where it might be useful.

Hi Julius ! Thanks for amazing videos. I'm doing a project for my postgraduate in which I've install minikube and running a docker container based service on my local host 3001. The service is accessible through web browser and perfectly working. I want to enable this service monitoring enable at Prometheus but state shows down at localhost:9090/target even though ive mentioned localhot:3001 as my target under scrape configs. I'm pretty confused what to do ? should I enable any other option ? please guide ?

Hi Julis, I'm having trouble fetching metrics from the target host RHEL 8. I've installed the Node Exporter on RHEL and it's running fine. I've verified the metrics using the navigator, and they seem to be working. However, when I declared the host from my Ubuntu server to Prometheus, the targets always show as down, with no host detected. (no rout )
